Spring Boot-yaml格式，eureka客户端配置default-zone报错问题

本文为joshua317原创文章,转载请注明：转载自joshua317博客 Spring Boot-yaml格式，eureka客户端配置default-zone报错问题 - joshua317的博客

一、问题

在配置eureka客户端的时候，设定好eureka客户端的简单配置，配置如下：

server:port: 8081error:path: ./logs/error
eureka:client:service-url:default-zone: http://eureka.joshua317.com/eureka/

结果运行后，报了以下错误：

看了下报错信息，主要原因是没有获取到配置里面的eureka服务eureka.service-url，而是走了eureka默认的服务地址http://localhost:8761/eureka/，然后默认的的确没有这个服务，就导致报错

2021-09-29 15:55:15.705  INFO 12672 --- [           main] c.n.d.s.t.d.RedirectingEurekaHttpClient  : Request execution error. endpoint=DefaultEndpoint{ serviceUrl='http://localhost:8761/eureka/}, exception=I/O error on GET request for "http://localhost:8761/eureka/apps/": Connect to localhost:8761 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect; nested exception is org.apache.http.conn.HttpHostConnectException: Connect to localhost:8761 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect stacktrace=org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://localhost:8761/eureka/apps/": Connect to localhost:8761 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect; nested exception is org.apache.http.conn.HttpHostConnectException: Connect to localhost:8761 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connectCaused by: org.apache.http.conn.HttpHostConnectException: Connect to localhost:8761 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect

但是为什么没有获取到配置里面的地址，而走了默认的服务地址呢？接下来我们来看看是何原因呢？

二、版本说明

首先说明下此次出现问题的软件版本说明

Spring Boot: v2.5.5

Spring Cloud: 2020.0.4

jdk:1.8

pom.xml文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.5.5</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.joshua317</groupId><artifactId>demo</artifactId><version>0.0.1-SNAPSHOT</version><name>demo</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version><spring-cloud.version>2020.0.4</spring-cloud.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-client</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><excludes><exclude><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></exclude></excludes></configuration></plugin></plugins></build></project>

三、解决

为了避免问题分析过程繁琐，先说解决方案，把问题解决后再去看原理

方案一：

把配置里面的default-zone换成defaultZone

server:port: 8081error:path: ./logs/error
eureka:client:service-url:defaultZone: http://eureka.joshua317.com/eureka/

方案二：

指定eureka.client.region，eureka.client.availability-zones等属性值

server:port: 8081error:path: ./logs/error
eureka:client:region: defaultavailability-zones:default: default-zoneservice-url:default-zone: http://eureka.joshua317.com/eureka/

其中，eureka.client.region属性可理解为是地理上的分区，比如北京，上海这种,或者可以自定义，一个服务只能属于一个Region；

eureka.client.availability-zones属性就是可用的Zone的集合，Zone表示一个区域，常用于实现不同网络分区的实例配置，已实现负载均衡的区域亲和性。一个Region可以包含多个Zone

eureka.client.service-url属性就是服务的url，eureka的服务地址

比如我们可以如下配置,设置多个zone，每个zone对应一个eureka服务地址

server:port: 8081error:path: ./logs/error
eureka:client:region: beijingavailability-zones:beijing: beijing-zone1,beijing-zone2,beijing-zone3service-url:beijing-zone1: http://eureka-server1:8761/eureka/beijing-zone2: http://eureka-server2:8762/eureka/beijing-zone2: http://eureka-server3:8763/eureka/

具体使用哪个方案，可根据我们项目的实际情况进行选择

拓展：

eureka.instance.lease-renewal-interval-in-seconds控制心跳周期间隔时间,如：eureka.instance.lease-renewal-interval-in-seconds=30；

eureka.instance.lease-expiration-duration-in-seconds控制服务时效的时间，指定距离最后一次心跳时间多少秒后未续约，则让注册中心剔除实例（需要同时关闭保护模式才能使过期节点被剔除），如：

eureka.instance.lease-expiration-duration-in-seconds=120

四、问题分析

我们第一部分问题的时候提到配置没有获取到，没有生效，既然问题源于配置文件没有生效，那么Spring Boot是如何加载配置的呢eureka.clinet的配置文件呢?现在我们来分析下eureka客户端获取配置的原理。

我们通过ctrl+shift+N搜索下eureka相关的文件，找到EurekaClientConfig，可以看到是一个interface接口文件,看下这个文件的内容

//
// Source code recreated from a .class file by IntelliJ IDEA
// (powered by Fernflower decompiler)
//package com.netflix.discovery;import com.google.inject.ImplementedBy;
import com.netflix.discovery.shared.transport.EurekaTransportConfig;
import java.util.List;
import javax.annotation.Nullable;@ImplementedBy(DefaultEurekaClientConfig.class)
public interface EurekaClientConfig {int getRegistryFetchIntervalSeconds();int getInstanceInfoReplicationIntervalSeconds();int getInitialInstanceInfoReplicationIntervalSeconds();int getEurekaServiceUrlPollIntervalSeconds();String getProxyHost();String getProxyPort();String getProxyUserName();String getProxyPassword();/** @deprecated */boolean shouldGZipContent();int getEurekaServerReadTimeoutSeconds();int getEurekaServerConnectTimeoutSeconds();String getBackupRegistryImpl();int getEurekaServerTotalConnections();int getEurekaServerTotalConnectionsPerHost();String getEurekaServerURLContext();String getEurekaServerPort();String getEurekaServerDNSName();boolean shouldUseDnsForFetchingServiceUrls();boolean shouldRegisterWithEureka();default boolean shouldUnregisterOnShutdown() {return true;}boolean shouldPreferSameZoneEureka();boolean allowRedirects();boolean shouldLogDeltaDiff();boolean shouldDisableDelta();@NullableString fetchRegistryForRemoteRegions();String getRegion();String[] getAvailabilityZones(String var1);List<String> getEurekaServerServiceUrls(String var1);boolean shouldFilterOnlyUpInstances();int getEurekaConnectionIdleTimeoutSeconds();boolean shouldFetchRegistry();default boolean shouldEnforceFetchRegistryAtInit() {return false;}@NullableString getRegistryRefreshSingleVipAddress();int getHeartbeatExecutorThreadPoolSize();int getHeartbeatExecutorExponentialBackOffBound();int getCacheRefreshExecutorThreadPoolSize();int getCacheRefreshExecutorExponentialBackOffBound();String getDollarReplacement();String getEscapeCharReplacement();boolean shouldOnDemandUpdateStatusChange();default boolean shouldEnforceRegistrationAtInit() {return false;}String getEncoderName();String getDecoderName();String getClientDataAccept();String getExperimental(String var1);EurekaTransportConfig getTransportConfig();
}

通过查看，发现有一个List对象的方法：getEurekaServerServiceUrls

我们看下是哪个类实现了这个接口，经查找EurekaClientConfigBean类实现了该接口的方法

接下来，我们断点看一下，发现myZone的值为defaultZone而不是default-zone，有两个serviceUrl,分别是default-zone和defaultZone

default-zone -> http://eureka.joshua317.com/eureka/

defaultZone -> http://localhost:8761/eureka/

在没有制定region的情况下，会使用defaultZone从ServiceUrl中查询Eureka Server的URL列表,所以使用代码默认初始化的地址http://localhost:8761/eureka/，所以出现了上面的错误。

具体为什么呢，我们接着往下走，进入到了EndpointUtils类中的getServiceUrlsMapFromConfig,我们可以看到region为us-east-1默认值

instanceZone="defaultZone"
region="us-east-1"
zone="defaultZone"
availZones[myZoneOffset]="defaultZone"

因为没有在yml配置region属性，所以才使用了默认us-east-1,并且availabilityZones为空。所以myZone使用的是默认是值defaultZone,详情见getZone()方法。

然后我们继续追代码，找到了类ConfigClusterResolver的getClusterEndpointsFromConfig方法，在这里面我们可以看到myZone的获取

那有人可能会问为什么service-url就可以呢，我们在EurekaClientConfigBean类中setServiceUrl方法处断点看下

在EurekaClientConfigBean调用sercviceUrl之前，先经过 BeanProperty.setValue()处理了，并且beanProperty对象的setter方法正好sercviceUrl，而BeanProperty的属性name是service-url这和我们的配置文件是一样的。

五、总结

在我们配置文件写入配置的过程中，属性里面的一些键名是驼峰，还是中划线，主要看我们底层代码实现是如何处理的，我们可以通过断点追代码进行排查分析。
